WhatsApp AI Chatbot n8n Workflow

What it does

WhatsApp AI Chatbot n8n Workflow overview

This WhatsApp AI chatbot receives customer messages through the WhatsApp Business API, retrieves relevant information from your approved knowledge base, drafts a response with GPT-4o, and hands complex conversations to a person with the context intact. Conversation logging and a post-resolution rating step keep the workflow operationally useful beyond the first reply.

Who it is for
